Application filed February 24,1916. Serial No. 80,141.

spring handles and is especially adapted for use for carrying packages,suit cases and the like. l

By the use of our vinvention we produce a handle comprising a ispringhaving a primary spiral coil and secondary reverse coils, the preferredembodiment of our invention being formed of a single strand of wirehaving the primary spiral coil formed at its center, the reverse coilsbeginning at the opposite ends of the primary coil with the ends thereofrabutting each other'at the center of the primary coil and the handlehaving at each end of the spring a hoo: forn ed of both strands of thewire formed intermediate the primary and secondary coils, so that anequal pull will be exerted on the primary and reverse coils fromopposite ends of the handle when the same is attached to a package orother load. in said preferred embodiment we preferably provide a seatfor the spring comprising a cylindrical steel casing arc-shaped inlongitudinal conformation, a springv of the character hereinabovedescribed within said casing with the hooks extending upon the outsidethereof at opposite ends, and said casing is then covered with leatheror other suitable material according to the use for which the handle isto be employed.

Referring now to these drawings in which similar reference charactersdesignate corresponding parts throughout the several views, Figure 1illustrates in side elevation a portion of a strandof wire so spirallycoiled as to form a portion of the primary coil of our improved handle;Fig. 2 is a similar view of a wire strand spirally coiled at one side toillustrate both the primary and secondary, reverse windings togetherwith the intermediate double-strand hook,

and at the other side said strand being coiled to illustrate the primarycoil only, spaces being left for the secondary, reverse coil. Fig. 3 isa longitudinal section of a handle embodying our invention andillustrating cur double-wound spring seated within an arc-shaped,cylindrical casing having a coveringof flexible material; Fig.v e is aperspective View of one end of our' double-wound spring 'p illustratingthe double-strand hook and the'beginning of the reverse coil at oneside; and 5 is a sectionon the line -rof Fig. 3.

Referring now tothese drawings, lindi-l catesa strand of wire which isinitially spiraliy coiled, preferably at its central portion, to providewhat we shall term'a pri-Y mary coil which as show-n is of such openconstruction 'or has its rings or windings 2 so Vrelatively spaced as topermit the seating between the windings of the primary coil of thewindings 8 of a secondary or reverse coil or coils. lreferably thesecondary, reversecoils are wound or woven in between the strands'2 ofthe primary coil after the formation intermediate the primary andsecondary, reverse coils of a double-strandhook l formed at oppositeends the spring handle. Y ln the preferred embodiment of our'inventionthe spring handle is seated within a cylindrical casing 5, preferablystamped up out of sheet metal, and bent longitudi-V nally in the form ofan arc or crescent. This casing 5 is preferably provided with a coveringG of leather or similar material, and the hooks e extend on oppositesides of said covered casing. @bvioiisly a. handle of the characterhereinabove described will, when employed to carry a load as, forexample, a suit-case or trunk, take up and compensate for'strains orshocks which may occur in the course of carrying the load.

Having described our invention, we claim:

l. A spring comprising a primary rspiral coil having its windingssuitably spaced and a secondary coil of similar diameter having itswindings seated` between and intermeshcentral portion and secondarycoils formed on opposite sides of the primary coil and coiled inopposite directions toward the center of the primary coil, saidsecondary coils having their windings seated between and intermeshingwith the windings of the pri mary coil. Y

t. A spring comprising a single strand of wire having a p imary coilformed from its central portion, secondary coils formed on oppositesides of the primary coil and coiled in opposite directions toward thecenter of the primary coil, said secondary coils having their windingsseated between and interineshing with the windings of the primary coiland hooks at opposite ends of said spring formed by doubling the strandintermediate the primary and secondary coils.

5. A spiral spring arc-shaped in conformation coinprising a singlestrand of wire having-a primary coil formed from its central portion,secondary, reverse coils formed on opposite sides of the primary ceilingand coiled in opposite directions toward the center of the primary coil,said reverse coils having their windings seated between and intermeshingwith the windings of the primary coil and hooks at opposite ends of saidspring formed by doubling the strand intermediate the primary andreverse coils.

6. A metallic casing cylindrical in cross section and arc-shaped inlongitudinal conp formation, a covering of leather or like material forsuch casing, a spiral spring seated within said casing having attachingmeans extending without the casing on opposite sides.

7. A spiral spring formed of a single Y strand o'f wire having a primarycoil formed from its central portion, reverse coils formed Y In witnesswhereof, we have signed our names to the foregoingv specification in thepresence of two subscribing witnesses.
